Course Outline: Recommended Books

Human-Computer Interaction by Jenny Preece, Yvonne Rogers, Helen Sharp, David Benyon

Review: An overview of the HCI field, illustrating the benefits of a user- oriented approach to the design of modern computer systems and emphasizing the design of interactive systems. Describes the interplay between people and computers in applications such as multimedia, virtual environments, and computer-supported cooperative work, and includes interviews with leading researchers in the field. For students of computer science, psychology, and cognitive science.

Course Outline: Recommended Books (cont.)

Human-Computer Interaction by Alan J. Dix (Editor), Janet E. Finlay, Gregory D. Abowd (Contributor), russel Beale, Janet E. Finley (Contributor), Russell Beale

Review: Extensively revised and rewritten in light of recent advances, this best-selling book is a comprehensive examination of human-computer interaction. It provides a multi-disciplinary approach to the subject through a synthesis of computer science, cognitive science, psychology and sociology, and stresses a principled approach to interactive systems design that fits a software engineering environment.

25

Module 1: Introduction to HCI

Human-Computer Interaction (HCI) is about designing computer systems that support people so that they can carry out their activities productively and safely. (Preece, p.1)

HCI studies human performance in the use of computer and information systems. This is a rapidly expanding research and development area.

26

M1: Introduction to HCI H… C… I…

Human- the end-user of a program- the others in the organization

Computer- the machine the program runs on

Interaction- the user tells the computer what they want- the computer communicates results

27

M1: Introduction to HCI Definition of HCI

Human-computer interaction is a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them.

(ACM SIGCHI, 1992, p.6)

Other terms: user interface, man-machine interface, ergonomics, human factors

28

M1: Introduction to HCI Overview of HCI

29

M1: Introduction to HCI Why is HCI Important?

HCI has a role in the design and development of all kinds of computer systems.

Harnessing the computer’s power is a task for designers who understand the technology and are sensitive to human capacities and needs (human factors).

Applications developers who apply human- factors principles and processes are producing exciting and useful interactive systems.

“HCI is the neither the study of humans nor the study of technology, but rather the bridging between those two.” Preece, p42.

33

M1: Introduction to HCI Specific Human factors Design Goals

Preece (p.14-15) describes “the goals of HCI are to produce usable and safe systems, as well as functional systems”.

Goals include:o Safety (eg safety-critical systems)o Utility (functionality)o Effectiveness (intuitive)o Efficiency (task achievement)o Usability (easy to learn and use)
